TECHNICAL FIELD

The present disclosure relates to an electronic device. More particularly, the present disclosure relates to an electronic device that includes a display with a bent or curved area.

BACKGROUND

With the advancement of electronic communication technologies, electronic devices having various functions have appeared. Such electronic devices generally have a convergence function that performs one or more function compositely.

As the functional differences between electronic devices of respective manufacturers have recently been greatly reduced, the manufacturers tend to make an effort to increase the rigidity of the electronic devices, which are being gradually slimmed in order to satisfy consumers' purchasing needs, and to strengthen the design features of the electronic devices. As a part of the effort, various structures (e.g., exteriors) of the electronic devices are at least partially implemented by using a metal material so as to appeal to the luxuriousness and elegance of the exterior of electronic devices.

In addition, terminal manufacturers make an effort to deliver intuitive and diverse information to users through slimmed electronic devices, and as a part of the effort, the terminal manufacturers tend to release displays of various shapes to display information.

Further, the manufacturers make an effort to address, for example, a weakened rigidity issue, a ground issue (e.g., an electric shock issue), and the issue of reduced antenna radiating performance, which are encountered when a metal material is used.

Electronic devices of the related art have adopted standardized planar displays as an information output means. Such displays promote information delivery merely by enlarging a screen thereof. As such, it is unavoidable that the entire volume of the electronic devices increase by the enlarged area of the display. In addition, since the standardized planar displays allow information to be confirmed in only one direction according to the disposed condition of the electronic devices, the information delivery capability is inevitably limited.

Therefore, a need exists for an electronic device that includes a display with a bent or curved area.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.

It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

By the term “substantially” it is meant that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.

The terms “have”, “may have”, “include”, or “may include” as used herein indicate the presence of disclosed corresponding functions, operations, elements, and the like, and do not limit additional one or more functions, operations, elements, and the like. In addition, the terms “include” or “have” indicate the presence of features, numbers, operations, elements, parts, or a combination thereof described in the specifications, and do not preclude the presence or addition of one or more other features, numbers, operations, elements, parts, or a combination thereof.

Herein, the term “user” may indicate a person who uses an electronic device or a device (e.g., an artificial intelligence electronic device) that uses the electronic device.

An electronic device of a single radio environment can provide long-term evolution (LTE) service using circuit switched fall back (CSFB) which determines whether paging information of a CS service network is received over an LTE network. When receiving a paging signal of the CS service network over the LTE network, the electronic device connects (or accesses) the CS service network (e.g., a 2nd generation (2G)/3^(rd) generation (3G) network) and provides a voice call service. For example, the 2G network can include one or more of a global system for mobile communications (GSM) network and a code division multiple access (CDMA) network. The 3G network can include one or more of a wideband-CDMA (WCDMA) network, a time division-synchronous CDMA (TD-SCDMA) network, and an evolution-data optimized (EV-DO) network.

Alternatively, the electronic device of the single radio environment can provide LTE service using single radio LTE (SRLTE) which determines whether the paging information is received by periodically switching every radio resource (e.g., receive antennas) to the CS service network (e.g., the 2G/3G network). Upon receiving the paging signal of the CS service network, the electronic device provides the voice call service by connecting the CS service network (e.g., the 2G/3G network).

Alternatively, the electronic device of the single radio environment can provide LTE service using single radio dual system (SRDS) which determines whether the paging information is received by periodically switching some of radio resources (e.g., receive antennas) to the CS service network (e.g., the 2G/3G network). Upon receiving the paging signal of the CS service network, the electronic device provides the voice call service by connecting the CS service network (e.g., the 2G/3G network).

FIG. 1 is a block diagram of a configuration of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 1 , an electronic device 100 includes a bus 110, a processor 120, a memory 130, an input/output interface 150, a display 160, and a communication interface 170. In various embodiments of the present disclosure, the electronic device 100 can omit at least one of the components or further include another component.

The bus 110 includes a circuit for connecting the components (e.g., the processor 120, the memory 130, the input/output interface 150, the display 160, and the communication interface 170) and delivering communications (e.g., a control message) therebetween.

The processor 120 includes one or more of a CPU, an AP, and a communication processor (CP). The processor 120 processes an operation or data on control of and/or communication with another component of the electronic device 100.

The processor 120, which is connected to the LTE network, determines whether a call is connected over the CS service network using caller identification information (e.g., a caller phone number) of the CS service network (e.g., the 2G/3G network). For example, the processor 120 receives incoming call information (e.g., a CS notification message or a paging request message) of the CS service network over the LTE network (e.g., CSFB). For example, the processor 120 being connected to the LTE network receives incoming call information (e.g., a paging request message) over the CS service network (e.g., SRLTE).

When receiving the incoming call information (e.g., a CS notification message or a paging request message) of the CS service network over the LTE network, the processor 120 obtains caller identification information from the incoming call information. The processor 120 displays the caller identification information on its display 160. The processor 120 determines whether to connect the call based on input information corresponding to the caller identification information displayed on the display 160. For example, when detecting input information corresponding to an incoming call rejection, through the input/output interface 150, the processor 120 restricts the voice call connection and maintains the LTE network connection. For example, when detecting input information corresponding to an incoming call acceptance, through the input/output interface 150, the processor 120 connects the voice call by connecting to the CS service network.

When receiving the incoming call information (e.g., a CS notification message or a paging request message) of the CS service network over the LTE network, the processor 120 obtains caller identification information from the incoming call information. The processor 120 determines whether to connect the call by comparing the caller identification information with a reception control list. For example, when the caller identification information is included in a first reception control list (e.g., a blacklist), the processor 120 restricts the voice call connection and maintains the connection to the LTE network. For example, when the caller identification information is not included in the first reception control list (e.g., the blacklist), the processor 120 connects the voice call by connecting to the CS service network. For example, when the caller identification information is included in a second reception control list (e.g., a white list), the processor 120 connects the voice call by connecting to the CS service network.

When receiving the incoming call information (e.g., a paging request message) of the CS service network over the LTE network, the processor 120 transmits an incoming call response message (e.g., a paging response message) to the CS service network. The processor 120 suspends the LTE service and receives the caller identification information (e.g., a CS call (CC) setup message) from the CS service network. The processor 120 determines whether to connect the call by comparing the caller identification information with the reception control list. For example, when the caller identification information is included in the first reception control list (e.g., the blacklist), the processor 120 restricts the voice call connection and resumes the LTE network connection. For example, when the caller identification information is not included in the first reception control list (e.g., the blacklist), the processor 120 connects the voice call by connecting to the CS service network. For example, when the caller identification information is included in the second reception control list (e.g., the white list), the processor 120 connects the voice call by connecting to the CS service network.

The memory 130 can include volatile and/or nonvolatile memory. The memory 130 stores commands or data (e.g., the reception control list) relating to at least another component of the electronic device 100. The memory 130 may store software and/or a program 140. The program 140 may include, for example, a kernel 141, middleware 143, an application programming interface (API) 145, and/or application programs (or “applications”) 147. At least some of the kernel 141, the middleware 143, and the API 145 may be referred to as an operating system (OS).

The kernel 141 controls or manages system resources (e.g., the bus 110, the processor 120, or the memory 130) used for performing an operation or function implemented by the other programs (e.g., the middleware 143, the API 145, or the applications 147). Furthermore, the kernel 141 provides an interface through which the middleware 143, the API 145, or the applications 147 connects the individual elements of the electronic device 100 to control or manage the system resources.

The middleware 143 functions as an intermediary for allowing the API 145 or the applications 147 to communicate with the kernel 141 to exchange data.

In addition, the middleware 143 processes one or more task requests received from the applications 147 according to priorities thereof. For example, the middleware 143 assigns priorities for using the system resources (e.g., the bus 110, the processor 120, the memory 130, and the like) of the electronic device 100, to at least one of the applications 147. For example, the middleware 143 may perform scheduling or load balancing on the one or more task requests by processing the one or more task requests according to the priorities assigned thereto.

The API 145 is an interface through which the applications 147 control functions provided from the kernel 141 or the middleware 143, and may include at least one interface or function (e.g., an instruction) for file control, window control, image processing, text control, and the like.

The input/output interface 150 functions as an interface that transfers instructions or data input from a user or another external device to the other element(s) of the electronic device 100. Furthermore, the input/output interface 150 outputs the instructions or data received from the other element(s) of the electronic device 100 to the user or an external electronic device.

The display 160 may include a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a micro electro mechanical system (MEMS) display, an electronic paper display, and the like. The display 160 displays various types of content (e.g., a text, images, videos, icons, symbols, and the like) for the user. The display 160 may include a touch screen and receive, for example, a touch, a gesture, proximity, a hovering input, and the like, using an electronic pen or the user's body part. The display 160 may display a web page.

The communication interface 170 can establish a communication between the electronic device 100 and an external electronic device (e.g., a first external electronic device 102, a second external electronic device 104, or a server 106). For example, the communication interface 170 can communicate with the first external electronic device 102 through a wireless communication or a wired communication 164, and also communicate with the second external electronic device 104, or the server 106 in connection to a network 162 through wireless communication or wired communication. For example, the wireless communication can conform to a cellular communication protocol including at least one of LTE, LTE-advanced (LTE-A), CDMA, WCDMA, universal mobile telecommunications system (UMTS), wireless broadband (WiBro), and GSM.

FIG. 6 is a view illustrating a manufacturing process of a housing according to various embodiments of the present disclosure.

Referring to FIG. 6 , a housing 604 may be manufactured through a process as follows. In the first operation, a metal 601, such as Al or Mg, is provided, and a portion to be filled by injection molding the housing and principal shapes may be processed. The processing may be performed through not only a computer numerical control (CNC), but also any other processing apparatus or method. In the second operation, a processed insert portion may be inserted into a mold so as to progress injection molding 602. Areas required for injection molding in the housing 604, such as a portion for antenna radiation and a portion for preventing electric shock, may be manufactured through the insert molding. In the third operation, it is possible to further process a shape additionally with a product which has been completely insert-molded 603. In such an operation, the metal and a molded product may be simultaneously processed, and only one of the metal and the molded product may be processed. In such an operation, the processing of operations in the corner portions of the housing (see FIGS. 7A to 7C) may progress. In the fourth operation, the above-described operations are completed and thus a complete product (a housing that includes a metal member and a non-metal member which are dually injection-molded) may be provided.

FIG. 7A is a configuration view illustrating a housing by a dual injection molding according to various embodiments of the present disclosure. FIG. 7B is a perspective view of a principal portion in which a portion is illustrated where a housing and a bracket are coupled to each other according to various embodiments of the present disclosure. FIG. 7C is a perspective view of a principal portion in which a portion of a bracket is illustrated which is coupled to a housing coupling portion in FIG. 7B according to various embodiments of the present disclosure.

Referring to FIGS. 7A to 7C, a housing 700, in which a non-metal member 720 is insert-molded to a metal member 710, may be provided. According to an embodiment of the present disclosure, the edge portions of the housing 700 (the portions illustrated by dotted lines in the four corner portions in FIG. 7A) may be formed in a shape corresponding to the edge portions of the front window. More particularly, each of the corner portions may be implemented in a curved shape, which is changed in the directions of all the three axes of the X, Y, and Z-axes. According to an embodiment of the present disclosure, when the housing 700 is manufactured by injection molding, the shapes of the corner portions and the inner portions of the corner portions may be easily manufactured according to the shapes of cavities of a manufactured mold. However, when the housing is manufactured using a metal, it is difficult to process the shape of each of the corner portions in the curved shape, which is changed in the directions of all the three axes of the X, Y, and Z-axes. More particularly, the inner portion of each of the corner portions is a portion that is mated in shape with the bracket, and may cause an assembly issue due to a processing deviation, and the like when it is processed as a 3-dimensionally curved surface.

Accordingly, when the inner portion of each corner of the housing 700 is formed in a single planar shape in order to facilitate assembly and to reduce a processing deviation, the processed area may be widened so that the processing time increases, and a deformation may be caused in the product according to the processing. Accordingly, by processing the inner portion of each corner portion stepwise such that the inner portion has a plurality of operation portions 701 to 704, it is possible to reduce the processing deviation that occurs during the processing of a 3-dimensionally curved surface, and to improve the long processing time that is required to process an end surface, the deformation of the product, and the like. According to an embodiment of the present disclosure, a counterpart (e.g., the bracket 730) that is mated in shape with the housing 700 may also be processed to have a plurality of corresponding operational portions 731 to 734. Through this, by making the corner portions of the housing and the corner portions of the bracket be strongly engaged with each other, it is possible to prevent the electronic device from being distorted, and by minimizing the deformation of the electronic device when an external impact is applied thereto, it is possible to prevent the front and rear windows, as well as the display module of the electronic device, from being destroyed.

According to an embodiment of the present disclosure, in the thickness w of the battery pack 1200, the lower thickness w2, except the thickness of the PCM unit 1230, may contribute to at least a part of a space, in which an electronic component for the display 1253 and the bracket 1252 for supporting the display 1253 are applied.

FIG. 15 is a view illustrating a disposed relationship between a PCM unit of a battery pack and electronic components according to various embodiments of the present disclosure.

Referring to FIG. 15 , when a sensor module and a flash device 1542 are arranged below a camera module 1540 as the electronic components, the battery cell 1510 of the battery pack 1500 may be disposed in parallel with the PCB 1560 and the camera device 1540 mounted on the PCB 1560. According to an embodiment of the present disclosure, the PCM unit 1530 of the battery pack 1500 may be disposed to overlap with the sensor module and the flash device 1542 which are mounted on the PCB 1560. According to an embodiment of the present disclosure, the sensor module and the flash device 1542 may be mounted on the top of the PCB 1560, and the PCM unit 1530 of the battery pack 1500 may be disposed on the bottom of the PCB 1560 to overlap with the sensor module and the flash device 1542. Accordingly, as compared to an existing mounting structure in which the battery pack 1500 is disposed in parallel with the PCB 1560, it is possible to secure a component mounting space or to increase the capacity of the battery cell 1510.

FIG. 16 is a configuration view illustrating a disposed relationship between a PCM unit of a battery pack and an electronic component according to various embodiments of the present disclosure.

Referring to FIG. 16 , a battery cell 1610 of a battery pack 1600 may be mounted to avoid a PCB 1660. For example, the battery cell 1610 may be disposed at least on the same plane as the PCB 1660. However, a PCM unit 1630, which is disposed to be weighted to the upper side of the battery cell 1610, may be disposed to be at least partially overlapped with and to be electrically connected to the PCB 1600. In addition, on the PCB 1660, a socket device as an electronic component 1670 may be mounted around an area in which the PCM unit 1630 of the battery pack 1600 is disposed. According to an embodiment of the present disclosure, the socket device may accommodate a card-type external device (e.g., a SIM card, a UIM card, a card-type memory, and the like).

According to various embodiments of the present disclosure, the PCM unit 1630 of the battery pack 1600 is disposed to overlap with the top portion of the PCB 1660, and the socket device is disposed in parallel with the PCM unit 1630 at a side of the PCM unit 1630 so that the wiring space shortage of the PCB 1660, which is caused due to the PCM unit 1630 of the battery pack 1600, can be addressed.

FIGS. 17A and 17B are configuration views illustrating a disposed relationship between a PCM unit of a battery pack and a PCB of an electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 17A and 17B, a pouch terrace 1730 having a certain width and length may be formed on the top of a battery pack 1700. According to an embodiment of the present disclosure, a PCM unit 1731 may be disposed at one side of the pouch terrace 1730, and a connection terminal portion 1732 may be formed to be drawn out by a certain length so as to be electrically connected to a PCB 1750 at the other side of the pouch terrace 1730. According to an embodiment of the present disclosure, the connection terminal portion 1732 may be disposed to be individually drawn out along the pouch terrace 1730 at a side of the pouch terrace 1730, rather than being directly drawn out from the PCM unit 1731.

According to various embodiments of the present disclosure, the PCM unit 1731 may be formed to have a relatively small height and disposed in parallel with the PCB 1750, and the connection terminal portion 1732 may be electrically connected to a side of the PCB 1750 to avoid the camera device 1740. Accordingly, the battery pack 1700 is disposed in a state where the connection terminal portion 1732 and the PCM unit 1731 are separated from the battery cell 1710 so that the volume of the PCM unit 1731 can be reduced so as to increase the capacity of the battery pack 1700 and the area of the PCB 1750 can be increased so as to secure a wiring space.

According to various embodiments of the present disclosure, there is provided a portable electronic device that may include a front glass cover that forms a front surface of the electronic device, a rear cover that forms a rear surface of the electronic device, a side surface unit that surrounds a space that is formed by the front glass cover and the rear cover, a display module that is embedded in the space and includes a screen area exposed through the front glass cover, a PCB that is disposed between the display module and the rear cover, and includes an opening that is at least partially closed, a battery that is installed within the opening and interposed between the display module and the rear cover, and a PCM that is positioned between the PCB and the display module, and is disposed close to one side of the battery when viewed from a position above the PCB.

According to various embodiments of the present disclosure, the rear cover and the side surface unit may be formed integrally with each other.

According to various embodiments of the present disclosure, the rear cover and the side surface unit may include the same material. According to an embodiment of the present disclosure, the material may be a metal.

According to various embodiments of the present disclosure, the electronic device may further include a camera module that is disposed close to the one side of the battery and one side of the PCM when viewed from a position above the PCB. The camera module includes a portion interposed between the display module and the rear cover. The camera module may include a lens that is exposed through the rear cover.

According to various embodiments of the present disclosure, the electronic device may further include a camera flash and/or a biometric sensor which are disposed at the one side of the battery to at least partially overlap with the PCM when viewed from a position above the PCB, and are positioned between the PCB and the rear cover.

According to various embodiments of the present disclosure, the PCM and the camera module are positioned side by side at the one side of the battery when viewed from a position above the PCB, and at least a part of the camera flash and/or the biometric sensor and the PCM may be positioned at opposite sides of the PCB, respectively, when viewed from a cross-section.

According to various embodiments of the present disclosure, the electronic device may further include a camera module that is formed through the PCB and disposed close to the one side of the battery when viewed from a position above the PCB, and includes a lens exposed through the rear cover. The PCM may have an L shape that includes a first portion that is positioned between the camera module and the battery when viewed from a position above the PCB.

According to various embodiments of the present disclosure, the electronic device may include at least one physical key button that is disposed to be at least partially exposed to the outside. According to an embodiment of the present disclosure, the key button may be configured as a volume button that is disposed on one side of the electronic device and performs a volume up/down function. According to an embodiment of the present disclosure, the key button may also be disposed on the other side of the electronic device and may perform a power ON/OFF function, a wake-up/sleep function, and the like.

A method of assembling a key button according to the related art may include a method of assembling the key button from the outside of the electronic device, and a method of assembling the key button from the inside of the electronic device.

According to various embodiments of the present disclosure, the method of assembling the key button from the outside of the electronic device is a method in which an FPCB is attached to a main instrument (e.g., the housing of the electronic device) and the key button is fitted from the outside. In such a case, it is advantageous in that since the key button and the FPCB can be assembled to one instrument, the performances of the key button, such as the click feeling and the life span of the key button, can be performed prior to assembling the electronic device. However, it is disadvantageous in that scratches may occur on the exterior of the electronic device when the button of the key button is assembled from the outside of the electronic device. In addition, when the key button is assembled from the outside of the electronic device, the key button may be separated to the outside of the electronic device since the locked amount of the key button is small.

According to various embodiments of the present disclosure, the method of assembling the key button from the inside may include assembling the key button to the main instrument (e.g., the housing of the electronic device) first, assembling the FPCB to the other instrument (e.g., the bracket), and assembling two instruments with each other. In such a case, the key button and the FPCB are assembled to different instruments (e.g., the housing and the bracket). Accordingly, there is a disadvantage in that in order to test the performances of the key button, it is necessary to assemble one preassembly (e.g., the assembly of the housing and the bracket), and when a defect occurs, it is necessary to dissemble the preassembly again.

According to various embodiments of the present disclosure, it is possible to provide a key button assembly structure to address the above-described problems. According to an embodiment of the present disclosure, it is possible to provide a key button assembly structure that can be implemented such that a key performance test is enabled in a single product state while assembling the key from the inside of the electronic device.

Hereinafter, a configuration of a key button according to an embodiment of the present disclosure will be described below.

FIGS. 18A and 18B are configuration views of a key button according to various embodiments of the present disclosure.

Referring to FIGS. 18A and 18B, a key button 1800 may include a key top 1810, and a key base 1820 that is fixed to the key top 1810.

According to various embodiments of the present disclosure, the key top 1810 may be formed of at least one of a metal material and a synthetic resin material. According to an embodiment of the present disclosure, the key top 1810 is disposed to be partially exposed to the outside of the electronic device (e.g., a side surface) so that a corresponding function of the electronic device (e.g., a volume up/down function, a wake-up/sleep function, a power ON/OFF function, and the like) may be performed by the user's pushing operation.

According to various embodiments of the present disclosure, the key base 1820 may be fixed to the bottom of the key top 1810. According to an embodiment of the present disclosure, the key base 1820 may serve as a locking member that allows the key top 1810 to be partially exposed from the electronic device while preventing the key top 1810 from being completely separated. According to an embodiment of the present disclosure, the key base 1820 may include a press portion 1821 that is formed on the bottom surface of the key base 1820 to protrude. According to an embodiment of the present disclosure, the press portion 1821 may be disposed so as to press a dome key (e.g., a metal dome key) 1852 (see FIG. 19 ) that is disposed on an FPCB 1850 (see FIG. 19 ) of a FPCB assembly 1830 (see FIG. 19 ) to be described later. According to an embodiment of the present disclosure, the key base 1820 may include support pieces 1822 that are formed to protrude on the opposite sides of the press portion 1821, respectively. According to an embodiment of the present disclosure, the support pieces 1822 may serve to prevent the key top 1810 from being excessively inserted when the key top 1810 is pressed, and to support the press portion 1821 to smoothly press the dome key 1852. According to an embodiment of the present disclosure, the key base 1820 may be formed of an elastic material. According to an embodiment of the present disclosure, the key base 1820 may be formed of at least one of rubber, silicon, and urethane.

According to an embodiment of the present disclosure, the key top 1810 and the key base 1820 may be integrally formed as one member using a single material. Without being limited thereto, however, a member formed of an elastic resin material may be formed on the key top formed as a metallic member, through insert molding.

FIG. 19 is a perspective view illustrating an FPCB assembly in a disassembled state according to various embodiments of the present disclosure.

Referring to FIG. 19 , the FPCB assembly 1830 may include a support plate 1840 and an FPCB 1850 supported by the support plate 1840.

According to various embodiments of the present disclosure, the FPCB 1850 may include a circuit body 1851 attached to the support plate 1840, and a connection terminal portion 1853 drawn out from the circuit body 1851 and connected to the PCB of the electronic device. According to an embodiment of the present disclosure, on the circuit body 1851, a dome key (e.g., a metal dome key) 1852 may be disposed. According to an embodiment of the present disclosure, the dome key 1852 may be disposed at a position corresponding to the press portion 1821 of the above-described key base 1810, and may perform an electric switching function by being pressed by the press portion 1821.

According to various embodiments of the present disclosure, the support plate 1840 may include a plate body 1841 that supports the circuit body 1851 of the FPCB 1850, and elastic pieces 1842 that are bent to a certain shape at the opposite ends of the plate body 1841. According to an embodiment of the present disclosure, the elastic pieces 1842 may have a “U” shape, and may have an inwardly or outwardly biased elasticity. According to an embodiment of the present disclosure, the elastic pieces 1842 may have the “U” shape and may have the elasticity to maintain the shape. Accordingly, when the elastic pieces are seated in elastic piece seating recess 2011 (see FIG. 20A) of a housing to be described later, the phenomenon, in which the support plate 1840 is separated from the housing, may be prevented in advance. According to an embodiment of the present disclosure, each elastic piece 1842 may include at least one fixing protrusion 1843 that protrudes from the outer surface thereof. The fixing protrusion 1843 may be fixed by being seated in an opening formed in the elastic piece seating recess 2011 so as to support the fixing of the support plate 1840. According to an embodiment of the present disclosure, the elastic pieces 1842 may be formed in various shapes, such as a “

” shape, a circular shape, an oval shape, and an “S” shape, besides the “U” shape. According to an embodiment of the present disclosure, the plate body 1841 of the support plate 1840 and the circuit body 1851 of the FPCB 1850 may be attached to each other through a method of bonding by using a double-sided tape, and the like.

FIGS. 20A to 20E are views illustrating a process of installing a key button and an FPCB assembly to a housing of an electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 20A and 20B, a housing (e.g., the rear housing) 2000 of the electronic device may be formed with a key top passage hole 2010. According to an embodiment of the present disclosure, the key top passage hole 2010 may be formed in a size that allows the key top 1810 of the key button 1800 to pass therethrough. According to an embodiment of the present disclosure, the key top passage hole 2010 may be formed in a size that allows only the key top 1810 to pass therethrough and prevents the key base 1820 fixed to the key top 1810 from passing therethrough. Without being limited thereto, however, a part of the key top may protrude so as to form a separation prevention flange.

According to various embodiments of the present disclosure, the key button 1800 may be lowered from the upper side of the housing 2000 in a direction indicated by the arrow as illustrated in FIG. 20A, and may be moved forward toward the key top passage hole 2010 as illustrated in FIG. 20B. By such an operation, the key button 1800 may be prevented from being completely separated from the key top passage hole 2010 of the housing 2000 by the key base 1820, and at the same time, the key top 1810 may be disposed such that the key top 1810 is partially exposed to the outside of the housing 2000 through the key top passage hole 2010.

Referring to FIG. 20C, while the key top 1810 of the key button 1800 is still partially passing through the key top passage hole 2010 of the housing 2000, the FPCB assembly 1830 may be mounted from the rear side in the direction indicated by the arrow. In such a case, the elastic pieces 1842, which are formed on the opposite ends of the support plate 1840 of the FPCB assembly 1830, may be tightly seated in the elastic piece seating recess 2011 that is formed in the housing 2000. This is because the elastic pieces 1842 are seated in the elastic piece seating recess 2011 while maintaining the outwardly biased elastic force. According to an embodiment of the present disclosure, each elastic piece seating recess 2011 may be formed with an opening (not illustrated), and the fixing protrusions 1843, which are formed to protrude from the elastic pieces 1842, respectively, may be seated in the openings, respectively, so as to support the support plate 1840 to be fixed to the housing 2000. According to an embodiment of the present disclosure, the plate body 1841 of the support plate 1840 may include a fixing plate 1844 that is formed to extend orthogonally to the plate body 1841. According to an embodiment of the present disclosure, when the support plate 1840 is fixed to the housing 2000, the fixing piece 1844 is seated in a fixing piece seating recess 2012 that is formed on the inner surface of the housing 2000, so that the support plate 1840, which is mounted on the housing 2000, can be prevented from moving left and right in advance.

Referring to FIGS. 20D and 20E, the key button 1800 mounted on the housing 2000 may hold the key top 1810 in the state in which the key top 1810 is partially exposed to the outside of the housing 2000, and the key button 1800 may be supported by the support plate 1840 of the FPCB assembly 1830 behind the key button 1800. According to an embodiment of the present disclosure, the press portion 1821, which is formed on the key base 1820 of the key button 1800, may maintain the state in which the press portion 1821 is in contact with the dome key 1852 of the circuit body 1851 that is supported by the plate body 1841 of the FPCB assembly 1830. In such a case, because the elastic pieces 1842 that are formed on the opposite ends of the support plate 1840 are fixed to the elastic piece seating recess 2011 formed in the housing 2000, the support plate 1840 is not moved back even if the key button 1800 is pressed, and by pressing the press portion 1821 of the key base 1820, only the dome key 1852, which is disposed on the circuit body 1851 of the FPCB 1850, may be pressed to be capable of being switched.

According to various embodiments of the present disclosure, because the pressing operation of the key top 1810 is implemented only by the support plate 1840 of the FPCB assembly 1830 without any other instrument (e.g., the bracket) in the state where the key button 1800 is assembled inside the housing 2000, the performance test of the key button 1800 can be easily implemented.

FIGS. 21A to 21D are configuration views illustrating a principal portion in a state where an FPCB assembly is installed in a housing of an electronic device according to various embodiments of the present disclosure. For the same constituent elements as those described above, descriptions will be omitted.

Referring to FIGS. 21A to 21D, the support plate 1840 of the FPCB assembly 1830 may be firmly fixed at the opposite ends thereof by the elastic pieces 1842, but may be moved left and right in the fixed state. Accordingly, on the plate body 1841 of the support plate 1840, the fixing piece 1844 may be bent in the direction orthogonal to the plate body 1841, and when the support plate 1840 is fixed to the housing 2000, the fixing piece 1844 may also be seated in the fixing piece seating recess 2012 that is formed in the housing 2000.

According to an embodiment of the present disclosure, the fixing piece seating recess 2012 may be formed in the form of an opening that penetrates the bottom surface of the housing 2000, and when the fixing piece 1844 is applied to the fixing piece seating recess 2012, the fixing piece 1844 may be seated such that the surface of the fixing piece 1844 and the bottom surface of the housing 2000 are flush with each other. According to an embodiment of the present disclosure, the fixing piece 1844 is formed in a rectangular shape. Without being limited thereto, however, the fixing piece 1844 may be formed in various angled shapes so as to prevent the support plate 1840 from being moved left and right. According to an embodiment of the present disclosure, one fixing piece 1844 is formed on the plate body 1841 of the support plate 1840. However, in the case where the plate body 1841 and a space of the housing 2000, which corresponds to the plate body 1841, are available, a plurality of fixing pieces 1844 may be formed.

FIG. 22 is a perspective view of an FPCB assembly in a disassembled state according to various embodiments of the present disclosure.

Referring to FIG. 22 , the above-mentioned FPCB assembly 1830 has been illustrated and described above with reference to one key button 1800, an FPCB 1850 having one dome key 1852 applied to the key button 1800, and a support plate 1840 that supports the FPCB 1850. FIG. 22 illustrates one FPCB assembly 2230 having two dome keys 2252 and 2253 that simultaneously support two key buttons 1800 that are separately applied, and hereinafter, the FPCB assembly 2230 will be described. Accordingly, the configuration of each of the two separately applied key buttons 1800 is the same as that of the key button 1800 illustrated in FIGS. 18A and 18B. Thus, the detailed descriptions for the configuration of the key buttons 1800 will be omitted.

Referring to FIG. 22 , the FPCB assembly 2230 may include a support plate 2240 and an FPCB 2250 supported by the support plate 2240.

According to various embodiments of the present disclosure, the FPCB 2250 may include a circuit body 2251 attached to the support plate 2240, and a connection terminal portion 2254 drawn out from the circuit body 2251 and connected to the PCB of the electronic device. According to an embodiment of the present disclosure, one pair of dome keys (e.g., metal dome keys) 2252 and 2253 may be disposed on the circuit body 2251 at a certain interval. According to an embodiment of the present disclosure, the one pair of dome keys 2252 and 2253 may be disposed at the positions corresponding to the press portions 1821, which are formed on the key bases 1820 of the individual key buttons 1800, respectively, and may be physically operated by pressing the press portions 1821 so as to perform an electric switching function.

According to various embodiments of the present disclosure, the support plate 2240 may include a plate body 2241 that supports the circuit body 2251 of the FPCB 2250, and elastic pieces 2242 that are bent in a certain shape on the opposite ends of the plate body 2241, respectively. According to an embodiment of the present disclosure, the elastic pieces 2242 may have a “U” shape and may have elasticity so that the leg portions of the “U” are biased to the outside in relation to each other. Accordingly, when the elastic pieces 2242 are seated in an elastic piece seating recess 2314 (see FIG. 23A) in a housing 2300 to be described later (see FIG. 23A), it is possible to prevent the support plate 2240 from being separated from the housing 2300 in advance. According to an embodiment of the present disclosure, each elastic piece 2242 may include at least one fixing protrusion 2243 that protrudes from the outer surface thereof, and the fixing protrusion 2243 may be fixedly seated in an opening formed in the elastic piece seating recess 2314 so as to assist the fixing of the support plate 2240. According to an embodiment of the present disclosure, the elastic pieces 2242 may be formed in various shapes that may exert elasticity, such as a “

” shape, a circular shape, an oval shape, and an “S” shape besides the “U” shape, by bending. According to an embodiment of the present disclosure, the plate body 2241 of the support plate 2240 and the circuit body 2251 of the FPCB 2250 may be attached to each other through a method of bonding a double-sided tape, and the like.

FIGS. 23A to 23E are views illustrating a process of installing key buttons and an FPCB assembly to a housing of the electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 23A and 23B, in a housing (e.g., a rear housing) 2300 of the electronic device, one pair of key top passage holes 2311 and 2312 may be formed at a certain interval. According to an embodiment of the present disclosure, the one pair of key top passage holes 2311 and 2312 may be formed to have a size that allows the key tops 1810 of the key buttons 1800 to pass through the key top passage holes 2311 and 2312, respectively. According to an embodiment of the present disclosure, the key top passage holes 2311 and 2312 may be formed to have a size that allows only the key tops 1810 to pass through the key top passage holes 2311 and 2312, respectively, and to prevent the key bases 1820 fixed to the key tops 1810 from passing the key top passage holes 2311 and 2312. Without being limited thereto, however, a part of each key top is formed to protrude so as to form a separation prevention flange.

According to various embodiments of the present disclosure, the key buttons 1800 may be lowered from the upper side of the housing 2300 in the direction indicated by an arrow as illustrated in FIG. 23A, and may be moved forward toward the key top passage holes 2311 and 2312, respectively, as illustrated in FIG. 20B. Through such an operation, the key buttons 1800 may be prevented from being completely separated from the key top passage holes 2311, 2312 of the housing 2300 by the key bases 1820, respectively, and at the same time, may be disposed such that the key tops 1810 are partially expose to the outside of the housing 2300 through the key top passage holes 2311 and 2312, respectively.

Referring to FIG. 23C, in the state where the key tops 1810 of the one pair of key buttons 1800 partially pass through the key top passage holes 2311 and 2312 of the housing 2300, respectively, the FPCB assembly 2230 may be mounted in the direction indicated by an arrow on the rear side of the key tops 1810. In such a case, the elastic pieces 2242 formed on the opposite ends of the support plate 2240 of the FPCB assembly 2230 may be tightly seated in the elastic piece seating recess 2314 formed in the housing 2300. This is because the elastic pieces 2242 are seated in the elastic piece seating recess 2314 while maintaining an outwardly biased elasticity. According to an embodiment of the present disclosure, the elastic piece seating recess 2314 may be formed with openings (not illustrated) and the fixing protrusions 2243, which are formed to protrude from the elastic pieces 2242, respectively, may be seated in the openings, respectively, so as to assist the support plate 2240 to be fixed to the housing 2300. According to an embodiment of the present disclosure, a plate support piece 2313 may be formed to protrude inside the housing 2300 so that the plate support piece 2313 can support the rear side of the plate body 2241 of the support plate 2240 as being mounted. According to an embodiment of the present disclosure, the plate support piece 2313 may prevent the support plate 2240 itself from being elastically moved backward in advance when the relatively long support plate 2240 is pressed by the key buttons 1800. According to an embodiment of the present disclosure, the plate support piece 2313 is preferably disposed between the one pair of key top passage holes 2311 and 2312, and a plurality of plate support pieces may be formed if a forming space is available.

Referring to FIGS. 23D and 23E, the one pair of key buttons 1800 mounted in the housing 2300 may be maintained in the state where each of the key tops 1810 of the key buttons 1800 is partially exposed to the outside of the housing 2300, and the key buttons 1800 may be supported by the support plate 2240 of the FPCB assembly 2230 from the rear side thereof. According to an embodiment of the present disclosure, the press portions 1821, which are respectively formed on the key bases 1820 of the key buttons 1800, may be maintained in the state of being respectively in contact with the dome keys 2252 and 2253 of the circuit body 2251 that is supported by the plate body 2240 of the FPCB assembly 2230. In such a case, because the elastic pieces 2242 formed on the opposite ends of the support plate 2240 are fixed to the elastic piece seating recess 2314 formed in the housing 2300, the support plate 2240 is not moved backward even if the key buttons 1800 are pressed, and only the dome keys 2252 and 2253 disposed on the circuit body 2251 of the FPCB 2250 can be physically switched by pressing the press portions 1821 of the key bases 1820.

According to various embodiments of the present disclosure, the housing of the electronic device may be manufactured through dual injection molding of dissimilar materials. According to an embodiment of the present disclosure, the housing may be formed by insert-molding a non-metal member to a metal member. According to an embodiment of the present disclosure, the non-metal member may be formed of a synthetic resin member.

According to various embodiments of the present disclosure, an electronic device that includes a housing including a metal portion in at least an area thereof may require an electric connection structure between a PCB disposed in the inner space of the electronic device and an antenna radiator that is generally disposed on the outer surface of the electronic device. Because the existing electric connection structures of an antenna carrier type, a laser direct structuring (LDS) type, and an FPCB type include a flexible antenna radiator so that they can be vertically connected to a pattern surface, and in the case of a direct print antenna (DPA) directly printed on the housing, because a vertical connection to a radiation pattern is not enabled, an electric connection can be achieved by using a separate metallic press-in pin.

However, the structure using such a press-in pin will additionally require a process of applying a separate structure, and may cause deterioration of a radiation performance of the antenna when a deviation and an error occur according to the assembly. Further, there are issues in that material costs increase due to added components, and the press-in pin cannot be applied to a complicated structure portion, and a peripheral portion may be scratched or deformed in the press-in process.

Further, the FPCB and antenna carrier type of the related art is flexible so that a pattern is movable from a radiation surface of an antenna radiator to a PCB contact surface. An issue may occur in securing a space that is absolutely necessary for pattern movement.

In addition, a screw structure of the related art may cause an electric shock issue. For example, an inner current may be transferred to an outer metal housing through a screw so than the user may be exposed to electric shock. In order to prevent this, a capacitor may be disposed around the screw as an electric safety device. However, this may cause the unit cost to increase, and a separate mounting space may be needed by adopting additional components.

Various embodiments of the present disclosure may provide a housing that is capable of addressing the above-mentioned problems only by a process of manufacturing the housing using a metal member and a non-metal member.

Various embodiments may implement conductive and insulative effects at a desired position only by the processes of insert-molding and processing a non-metal member to a metal member.
